specification.

Prior to my improvements the usual method ofrendering tricycle-seatsadjustable vertically has been to mount the saddle or its spring on avertical supporting-rod held by a clamp or set screw in a socketattached to the frame, and to secure fore-and-aft adjustment the seat orsad dle has been mounted on a plate or clamp and this upon a bent orinverted L-pin supported in the frame.

Now the object of my inventiouis to provide the seat or saddle or thespring or springs supporting the same with mechanism by which either orboth the fore-andaft or vertical adjustment may be readily effectedwithout weakening the frame or unnecessarily adding to it, and yet theseat be rigidly secured in any desired position, and by means that shallbe applicable, also, to the perches or backbones of bicycles, safeties,or other velocipedes without tapping or weakening the frame, and inposi: tions where the other method is impracticable.

I will now particularly describe my improvements as applied to acradle-spring and horizontal reach of a tricycle, as shown in theaccompanying drawings, in which Figure 1 shows my contrivance inperspective; and Fig. 2 shows parts of the same in verticalcross-section; and Figs. 3 and 4 show modifications, as will beexplained.

A is a seat-spring of bent and coiled wire, its main part in the form ofa cradle or Harrington spring; but instead of leavingthe ends a a shortand horizontal, as is usual, Iextend and bend them downward to form thevertical supporting-rods a a.

B is a loop or band made to fit the eylindri cal reach 0, or the part ofthe frame of the "elocipede above and upon which the spring A is to besupported, and partially, but not com- 7 pletely, to surround it. Thisband I prefer to make in two parts, stoutly hinged at b, and with thetwo free sides b 1) extending so as to nearly meet about the reach whenin position.

D D are lugs formed on or attached to the sidesof the loop B, bored at dd to form sockets to receive the rods aa vertically, or nearly so, andhaving mortises or openings (1 d dd" transversely to receive and permitthe operation of the grips F F and sleeve-nut G.

The grips F F, I prefer to make in the form of eyebolts, as shown inFigs. 1 and 2, the rods a Ct passing through the eyes, and with stemsf'f, right and left hand threaded, or else differentially threaded foreach cooperating pair.

G is a sleeve-nut having'the internal bore, 9, threaded to correspondwith. and fit upon the stemsff, and having also an annulus, g,\vithfacets for the application of a wrench.

\Vhen the parts are assembled, as shown, if the sleevenut be turnedin,one direction the parts are loosened and the spring may be adjustedvertically by raising or lowering the rods a a in their sockets, or thespring may be adjusted laterally or fore and aft by moving the loop B onthe reach 0, or both these adjustments may be made; and if thesleeve-nut be turned in the other direction the stems f f will bedrawntogether therein and the eyes of the grips drawn against the rods,and the latter against the lugs, and the loop against the reach till allthe parts be tightened seeurely together in position, as desired.

Instead of making the openings (2 in the.

lugs D, as shown in Fig. 1, I may make them, as shown in side elevationin Fig. 3, as closed mortises and insert the grips endwise.

Instead of a sleeve-nut and stemgrips, as shown in Figs. 1 and 2, I maymake the screwfastening devices, as shown in top plan in Fig. 4, toconsist of a stem-nut, G having right and left ordifi'erentialscrew-threaded stems g g?, .and a facet annulus, g, thereon, and makethe grips F F with the eyes f f for the rods to a to havetransversebores or sockets correspondingly threaded for the stems g 9and in either form of tightening device I may make only one stem, as for 9 threaded ICQ and its corresponding socket or sleeve end threaded,while the other is formed with aplain swivel-joint in any suitable form.It is also obvious that my improved clip and tightener may be used withany other form of spring, and that the rods a a, instead of being formedon the spring, may be made separate and attached thereto by means of aplate, or otherwise; also, that instead of arranging the rods onopposite sides of the clips, as shown, they may be both brought to thesame side, or only one supporting-rod may be used instead of two, andthat the two sides of the'loop may be held to the reach by separatebolts or fastening devices, and that the tightening devices F G, 850.,may be arranged parallel with instead of transversely to the sides ofthe loop B, and that the same clips and tighteners may be used onbicycles or other velocipedes as well as on tricycles, and applied toseats with; out springs, 850.; and. I do not mean to limit myself to theexact details, shapes, arrangements, or forms of construction .shown anddescribed, as others maybe observed without departing from the substanceof my invention.

I claim as new and of my invention- 1. A clip constructed with a loopfor partially surrounding the part to which it is to be attached andwith holding lugs and grips for the parts to be supported thereby, andwith means, substantially as set forth, operating between the lugs todraw the grips and the lugs together to secure the clip and the partssupported by it in position.

2. A clip with a loop constructed in two parts hinged together forpartially surrounding the part to which it is to be attached and withholding lugs and grips for the parts to be supported thereby, and withmeans, substantially as set forth, operating to draw the grips and thelugs together to secure the clip and the parts supported by it inposition.

3. A clip constructed with a loop for partially surrounding the part towhich it is to be attached and with a lug and mortise to receive a partto be supported thereby, and with a grip and sleeve or equivalent devicefor securing the supported part to the clip.

4. The combination, in a saddle clip, of a loop, as B, one or more lugs,as D, one or more grips, as F, and a screw device, as Gff, constructedto operate essentially as set forth.

5. The combination of a loop, as B, one or more lugs, as D, one or moregrips, as F, and a screw device, as Gff, and one or moresupporting-rods, as a, constructed to operate essentially as set forth.

6. A'velocipede spring constructed with a coiled wire branch, as a, anda downward portion, as a, to operate as a vertically adjustablesupporting-rorl and for attachment to a clip.

7. The combination of a coiled and bent wire seat-spring, as A,with alaterally-adjustable clip, as B D, and a tightening device, essentiallyas set forth.

8. The combination of a coiled and bent wire seat-spring, as A,with alaterally-adjustable clip and a vertically-adjustable support ing part,as a, and tightening device, as F G, and connections, essentially as setforth.
